Description

The present invention relates to a second agent composition for hair dyeing or bleaching. More specifically, it is a hair dyeing or bleaching second agent composition used by mixing with the hair dyeing or bleaching first agent composition at the time of use, which is excellent in stability at a high temperature and is stored at a low temperature. The present invention relates to a second agent composition for hair dyeing or bleaching, which has little change in viscosity even at times and does not affect the discharge property from a container.

Due to the growing awareness of fashion in recent years, hair coloring agents that can easily change the color of hair have been accepted by many people regardless of gender. There are various types of hair coloring agents such as permanent hair dyes, semi-permanent hair dyes, depigmenting agents and temporary coloring agents, and they are used according to their needs. Among them, permanent hair dyes and bleaching agents are excellent in hair dyeing and bleaching effects, and are hair coloring agents currently used by many people because of their characteristics.

As a permanent hair dye and a depigmenting agent, it comprises a first agent composition containing or not containing an oxidation dye and containing an alkaline agent, and a second agent composition containing an oxidizing agent such as hydrogen peroxide. The formulation formula is widely used. These can be applied to the hair by mixing the first and second composition for hair dyeing or bleaching in advance in a tray or bottle-shaped container immediately before use, or by using a brush or the like. There is a method of mixing on the hair.

Since the alkaline agent and the oxidizing agent cause a redox reaction in the first agent composition and the second agent composition for hair dyeing or decolorization when mixed, various containers (poly container, aluminum tube container, poly tube) are used until use. Stored separately in containers, aerosol containers, pouch containers, etc.). Therefore, the viscosities of the first agent composition for hair dyeing or decolorization and the second agent composition are appropriately set in consideration of the discharge property from the container. In the case of an emulsified composition, a higher alcohol having 12 to 24 carbon atoms is often used for adjusting the viscosity, and the higher alcohol also has an effect of enhancing emulsification stability.

Since the pH of the second agent composition for hair dyeing or bleaching containing an oxidizing agent is low, the stability over time tends to be lower than that of a general emulsified composition. In addition, it may be placed in a harsh environment during transportation or storage, and especially in summer, it may reach about 50 ° C (meaning high temperature in the present invention) due to the influence of temperature and reflected heat. In such a high temperature environment, the emulsified composition promotes coalescence and creaming, and is likely to cause separation. For this reason, emulsification stability at high temperatures is required, and several second agent compositions for hair dyeing or bleaching have been disclosed so far (Patent Documents 1 to 3).

By the way, the general room temperature when the air conditioner is used is around 20 ° C, but the room temperature when the heating device is not used in winter drops to about 5 ° C (meaning low temperature in the present invention). In some cases, the second agent composition for hair dyeing or bleaching may be stored for a long period of time in such an environment.

The second agent composition for hair dyeing or bleaching contains a higher alcohol having 12 to 24 carbon atoms from the viewpoint of viscosity adjustment and emulsion stability as described above. However, higher alcohols having 12 to 24 carbon atoms are promoted to crystallize in a low temperature environment, and the viscosity of the emulsified composition increases with time. Causes a decrease in (including simultaneous ejection property with the first agent composition for decolorization). Therefore, there is a need for a second agent composition for hair dyeing or decolorization, which is excellent in stability at high temperatures, has little change in viscosity even during low temperature storage, and does not affect the discharge property from the container.

However, in all the patent documents, the stability at high temperature has been studied, but the discharge property from the container at low temperature storage has not been considered.

Therefore, the present invention has been made in view of the above problems, and is a hair dyeing or bleaching second agent composition used by mixing with the hair dyeing or bleaching first agent composition at the time of use. It is an object of the present invention to provide a second agent composition for hair dyeing or bleaching, which is excellent in stability at high temperature, has little change in viscosity even at low temperature storage, and does not affect the discharge property from a container.
